Answer:
3/4
Step-by-step explanation:
Δy = y1 - y2 = 1 - (-2) = 3
Δx = x1 - x2 = -3 - (-7) = 4
Slope = Δy/Δx = 3/4
If B=0, and A≠0, then
Ax+C=0, or x=-C/A, a constant value.
This signifies L is a vertical line with slope ∞

Answer:
answer above or below is right
Step-by-step explanation:
Answer:
-1/2
Step-by-step explanation:
Im not going to go into detail about how to compute sin30 and cos 30, but know that sine and cosine are just the ratios between the sides of a 30-60-90 triangle with a hypothenuse of 1.
With that being said:
sin^2 30 - cos^2 30
= (1/2)^2 - ((sqrt3)/2)^2
= 1/4 - 3/4
= -1/2
